We can find the volume of the cylinder using the next equation:
[tex]V=\pi r^2h[/tex]Where h represents the height and r represents the radius.
The radius is the half value of the cylinder. Then :
r=d/2
r=7yd
r=3.5yd
Replacing:
[tex]\begin{gathered} V=\pi(3.5yd)^2(8yd) \\ V=98\pi yd^3 \end{gathered}[/tex]Hence, the volume is 98π yd³
98π yd³=307.9
The answer is decimal form is 307.9 ( The value is rounded to the nearest tenth).
